1.调用外部安装器安装
/**
* 外部应用安装器安装apk(原生接口)
* @param context
* @param path apk的路径
* @return
*/
public static boolean installApkByPath(Context context, String path) {
try {
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(new File(path)), "application/vnd.android.package-archive");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent);
return true;
} catch (Exception e) {
e.printStackTrace();
}
return false;
}
2.静默安装(系统应用才有权限)
这里使用反射的方式调用
public class PackageManager_R {
private static final String TAG = "PackageManager_R";
private static final String ERROR_TAG = "ReflectError " + TAG;
private static Method sMethod_installPackage;
/**
* 静默安装(原生接口)
*
* @param path
* @return
*/
public static boolean installPackage(String path, final SystemAppInstall.InstalledCallBack callBack) {
if (sMethod_installPackage == null) {
try {
sMethod_installPackage = PackageManager.class.getMethod("installPackage", Uri.class, IPackageInstallObserver.class, int.class, String.class);
} catch (Exception e) {
LogUtils.w(ERROR_TAG, "", e);
e.printStackTrace();
}
}
IPackageInstallObserver observer = new IPackageInstallObserver.Stub() {
public void packageInstalled(String packageName, int returnCode) {
if (returnCode != 1) {
callBack.onResult(packageName, false);
} else {
callBack.onResult(packageName, true);
}
}
};
PackageManager pm = AppContextUtils.getAppContext().getPackageManager();
try {
sMethod_installPackage.invoke(pm, Uri.parse("file://" + path), observer, 0, null);
return true;
} catch (Exception e) {
LogUtils.w(ERROR_TAG, "", e);
e.printStackTrace();
}
return false;
}
}
对应的源码的接口
/**
* @hide Install a package. Since this may take a little while, the result
* will be posted back to the given observer. An installation will
* fail if the calling context lacks the
* {@link android.Manifest.permission#INSTALL_PACKAGES} permission, if
* the package named in the package file's manifest is already
* installed, or if there's no space available on the device.
* @param packageURI The location of the package file to install. This can
* be a 'file:' or a 'content:' URI.
* @param observer An observer callback to get notified when the package
* installation is complete.
* {@link IPackageInstallObserver#packageInstalled(String, int)}
* will be called when that happens. This parameter must not be
* null.
* @param flags - possible values: {@link #INSTALL_FORWARD_LOCK},
* {@link #INSTALL_REPLACE_EXISTING},
* {@link #INSTALL_ALLOW_TEST}.
* @param installerPackageName Optional package name of the application that
* is performing the installation. This identifies which market
* the package came from.
* @deprecated Use {@link #installPackage(Uri, PackageInstallObserver, int,
* String)} instead. This method will continue to be supported
* but the older observer interface will not get additional
* failure details.
